What Is the Page Aerospace C734-01-030?
The Page Aerospace C734-01-030 is an emergency power supply battery pack designed specifically for Dassault Falcon business jets. This component provides backup power to emergency lighting systems—a safety-critical function that ensures illumination for evacuation routes, exit signs, and critical areas during main electrical system failures or emergency landings.
That backup function spans several Falcon platforms: the Falcon 50, Falcon 900, Falcon 900EX, Falcon 2000, and Falcon 2000EX. As a complete battery assembly, it stores and delivers electrical power through the aircraft's emergency power distribution network, activating automatically when the main system fails.
Why operators seek second-source alternatives:
- OEM discontinuation of legacy components as platforms age — the global fleet average reached 16.3 years in 2025
- Supply chain bottlenecks that cost the global airline industry an estimated $11 billion in 2025, with $3.1 billion attributed to maintenance costs alone
- AOG events running $10,000 to $150,000 per hour depending on aircraft type and route
- Single-source dependency on OEM pricing with no competitive alternative
Each of these pressures is exactly why the FAA-PMA framework exists: to give operators a certified, competitive alternative to OEM-only supply chains across commercial, corporate, and military aviation.
Why FAA-PMA Approval Is Non-Negotiable for This Part
What FAA-PMA Actually Means
Under 14 CFR Part 21 Subpart K, a Parts Manufacturer Approval (PMA) is a combined design and production approval issued by the FAA. It legally authorizes a manufacturer to produce replacement articles for installation on type-certificated aircraft. PMA parts carry the same airworthiness standing as OEM components—they're not alternatives or substitutes, but fully approved equivalents.
The Rigor Behind PMA Approval
The FAA doesn't rubber-stamp PMA applications. Manufacturers must prove compliance through one of two pathways:
- Identicality — the design is identical to the OEM article in every respect, with or without a licensing agreement
- Test and Computation — reverse engineering, comparative analysis, and validation testing confirm the part meets or exceeds original airworthiness standards
Both pathways require review by FAA engineers or a Designated Engineering Representative (DER), independent technical reviewers authorized by the FAA to evaluate design data and recommend approval only after thorough validation.
Why This Matters for Battery Components
Aircraft battery systems are safety-significant components under 14 CFR § 25.1353. Ni-Cd battery installations must:
- Maintain safe cell temperatures and pressures
- Prevent accumulation of explosive or toxic gases
- Feature automatic systems to control charging rates
- Disconnect the battery during over-temperature conditions or failures
A failure in emergency power supply systems can affect engine start capability, emergency systems, and critical avionics. For that reason, part provenance and approval status are subject to the same scrutiny as the component itself.
The Severe Risks of Unapproved Parts
The FAA actively investigates and prosecutes cases involving Suspected Unapproved Parts (SUPs). In 2019, the agency proposed a $203,100 civil penalty against GEE-BEE Aeroproducts for manufacturing and selling unapproved parts without required authorizations. Unapproved alternatives—surplus parts with unknown history, counterfeit hardware, components lacking traceability—pose catastrophic risks:
- Aircraft grounding by FAA inspectors
- Voided maintenance records
- Exposure to enforcement actions and civil penalties
- Unvalidated design that may fail in flight-critical situations
That's precisely why sourcing matters as much as the part number itself.
In-House Engineering Authority
Ni-Cad Systems' Vice President, Stephen Andrues, holds FAA Designated Engineering Representative (DER) credentials alongside his A&P mechanic and pilot certificates. The technical authority behind the company's 30+ PMA approvals is built into the organization, not contracted out. Buyers have direct access to the same engineering expertise that validated the part they're installing.
Ni-Cad Systems' Certified Replacement: Who's Behind It and Why It Matters
Ni-Cad Systems, Inc. is the source of the FAA-PMA approved replacement for the C734-01-030. Founded in 1974 and based in Hayward, California, this Part 145 repair facility has maintained exclusive focus on aircraft battery and power supply systems for over 50 years.
Portfolio depth and specialization:
- 30+ FAA-PMA approvals across NiCd batteries, temperature sensors, and modification kits
- 47,000+ units serviced since 1974—a concrete indicator of production volume, quality consistency, and field-proven reliability
- Single-category depth — aircraft battery systems are the only thing on the table, not a side offering from a general parts distributor
According to IMARC Group, the global commercial aircraft PMA market reached $11.4 billion in 2024 and is projected to grow to $15.6 billion by 2033. Within this expanding market, 74% of airlines now use PMA parts to mitigate supply chain challenges, prioritizing cost savings and availability equally.
What sets Ni-Cad Systems apart within this market is its position as both PMA holder and Part 145 repair station. That dual role means full visibility and accountability across design, manufacture, and service—no handoffs to brokers who lack manufacturing oversight, no gaps in the traceability chain.
Ni-Cad Systems serves corporate aviation, airlines, and military operators—customer segments that run structured procurement programs and hold suppliers to strict quality standards. For parts sourcing managers in those environments, that operational history is a faster path to approval than any spec sheet.
Traceability and Documentation: What Comes With Every Part
In aviation, traceability is proof of airworthiness. Every component installed on a type-certificated aircraft requires an unbroken documentation chain from manufacture to installation.
Every C734-01-030 replacement from Ni-Cad Systems ships with a complete documentation package:
- FAA Form 8130-3 — Airworthiness Approval Tag issued by an authorized Release Certifying Employee (RCE), confirming origin and conformity to approved design data
- Certificate of Conformance — Signed verification of compliance with all applicable specifications
- Test data sheets — Capacity and performance results from production validation testing
- PMA reference documentation — Ties the part directly to its FAA approval, including lot/batch control and inspection sign-offs at critical production stages
This package satisfies incoming inspection requirements under AC 20-62E, supports logbook entries per 14 CFR Part 43, and holds up under FAA audits, airline quality reviews, and military compliance checks.
Because Ni-Cad Systems is both the manufacturer and the Part 145 facility, documentation originates at the source—there are no intermediaries creating gaps, no brokers with incomplete records, no questions about origin or conformity.
